Intel Workload Services Framework EUVD-2026-56526

Exploitation requires ALL of the following concurrent conditions: (1) local access to the affected host - remote network exploitation is not possible per AV:L; (2) the Intel Workload Services Framework software must be installed and running; (3) a privileged user (PR:H) must be actively present or interacting with the system in a passive manner (UI:P - the user does not need to take a specific action but must have an active privileged session); (4) specific attack requirements must be present in the environment (AT:P), meaning an environmental or configuration precondition beyond the attacker's direct control must hold. The description specifies this occurs 'without special internal knowledge', meaning deep vulnerability knowledge is not required once the preconditions are met. Exploitation is LIMITED by: the requirement for local access (no remote exploitation), the mandatory presence of a highly privileged user session, and unspecified AT:P environmental conditions that must align. There is no indication that default-configuration deployments lacking co-resident privileged sessions are vulnerable in practice.

The CVSS 4.0 score of 5.4 (Medium) is materially lower than the C:H/I:H/A:H impact metrics would suggest in isolation, principally because three friction factors constrain exploitation: AV:L (local access only, eliminating remote attack surface), PR:H (a highly privileged user account must be present and interacting), and AT:P (specific attack requirements must be pre-existing in the environment). These combined constraints mean this is NOT a remote, opportunistic, or unauthenticated threat. EPSS data was not supplied, so exploitation probability is unknown. The vulnerability is not listed in CISA KEV, and no POC has been identified, lowering immediate urgency. The absence of subsequent-system impact (SC:N/SI:N/SA:N) means lateral movement or supply-chain contamination via this vector is not indicated. Real-world priority is LOW-TO-MEDIUM: organizations running Intel Workload Services Framework in environments where untrusted code shares a host with privileged users should patch, but this is not an emergency response item for most environments. The PR:H prerequisite is the critical gating factor - if privileged users are not co-located with untrusted workloads, the attack surface is negligible.

A local attacker deploys a malicious unprivileged process on a host running Intel Workload Services Framework - for instance, within a shared compute node - and waits for a privileged administrator to perform routine activity on the same system (passive user interaction). When the required attack preconditions are met and the privileged user session is active, the malicious process exploits the protection mechanism failure in the Ring 3 software layer to escalate its own privileges, achieving full system compromise. No public exploit code has been identified at time of analysis, so exploitation likely requires custom tooling with knowledge of the specific protection mechanism failure.
